DLC for Rock Band 2 on a PAL Wii/NTSC game

Hi guys.
So as the title reads, I have a PAL Wii and an NTSC copy of Rock Band 2 and I want some downloadable content.

I know that one solution is simply getting the PAL copy, but that's gonna be an extra 70-80 bucks I don't exactly want to spend. I've also heard of anyregion changer, but I've also heard that changing your shop region deletes all your current purchases without any chance of back-up/restoration.

Any help with my problem would be greatly appreciated

Thanks in advance.

Get an ISO for Rock Band 2 That is in PAL form. Since you already own a copy of Rock Band, It should still be legal. I get my ISO's from Maintenance , But they are having problems right now. Im making a BITgamer account, which is the same thing pretty much, So if its the ISO you want, I can download it for you and send a link soon. Hope any of this helps.

Yeah, if that works it'd be great, any help would really be appreciated
So if I get an ISO of the PAL version, do I just put my game CD directly in my disc drive and copy it over? Sorry for being a bit of a dimwit on this
